That Roland rig is very impressive. If I were in your situation I'd be more than happy to be able to play one of those. Years ago when I was doing the apartment living thing I bought a DTX-treme. I really wanted the Roland but it was just out of my budget. In hindsight, I wish I had just saved up longer for the Roland or just not have gotten anything at all. The DTX isn't terrible, though.
